3. Setup and Installation
The Strex SP156 saddle is designed for quick and easy installation on most standard bicycles, including city bikes, cruisers, mountain bikes, and electric bikes. Follow these steps to install your new saddle:
- Remove Old Saddle: Use an appropriate wrench to loosen the bolt(s) securing your old saddle to the seat post. Carefully remove the old saddle.
- Attach New Saddle: Place the Strex SP156 saddle onto the seat post clamp. Ensure the saddle rails are correctly seated within the clamp mechanism.
- Adjust Position: Adjust the saddle's forward/backward position and tilt to your preferred riding posture. A level saddle is a good starting point for most riders.
- Tighten Bolts: Securely tighten the seat post clamp bolts. Ensure the saddle is firmly attached and does not wobble. Do not overtighten, as this can damage the seat post or saddle rails.
- Final Check: Before riding, gently push down on the saddle and try to move it side-to-side to confirm it is securely fastened.
